Transmission efficiency limit of single-switch and cascaded reconfigurable transmitarray elements
Changhao Liu, Fan Yang, Shenheng Xu +1
Reconfigurable transmitarray antennas (RTAs) are rapidly gaining popularity, but optimizing their performance requires systematic design theories. In particular, establishing a per…
